(1) These pre-wiring kits cannot be used with reversing contactors.(2) Terminal blocks are supplied with terminals protected against direct finger contact and screws in the open, "ready-to-tighten" position.(3) To order a terminal block for connection by lugs, the reference becomes LA7D30646.(4) Remember to order the terminal block corresponding to the type of relay.(5) The time for which the coil of remote tripping or electrical resetting device LA7D03 or LAD703 can remain energised depends

on its rest time: 1 s pulse duration with 9 s rest time; 5 s pulse duration with 30 s rest time; 10 s pulse duration with 90 s rest time; maximum pulse duration 20 s with a rest time of 300 s. Minimum pulse time: 200 ms.

(6) Reference to be completed by adding the code indicating the control circuit voltage. Standard control circuit voltages (for other voltages, please consult your Regional Sales Office):

Volts 12 24 48 96 110 220/230 380/400 415/44050/60 Hz – B E – F M Q NConsumption, inrush and sealed: < 100 VAc J B E DD F M – –Consumption, inrush and sealed: < 100 W.(7) Only one terminal block can be mounted below LR9D.(8) Not compatible with 3-pole relays fitted with spring terminals.(9) LRD380, LRD3806 available end 2017.

Overload relays Motor and machine protection

IntroductionExceeding the operating limits of an electric motor will lead, eventually, not only to destruction of the motor itself but also of the mechanisms it drives.

This type of load can be the cause of electrical or mechanical faults. b Electrical faults: v overvoltage, voltage drop, imbalance and phase failure which cause variations in

the current drawn, v short-circuits which can cause the current to reach levels capable of destroying

the load.

b Mechanical faults: v locked rotor, v brief or prolonged overload which leads to an increase in the current drawn by

the motor, and therefore overheating. The cost of these faults must take into account loss of production, loss of raw materials, repair of the production tool, poor quality of production and delays in delivery.

These faults can also have dramatic consequences on the safety of persons in direct or indirect contact with the motor.

To prevent these faults, protection measures are necessary. They make it possible to isolate the equipment to be protected from the mains supply by measuring variations in electrical values (voltage, current, etc.).

Each motor starter must therefore have:

b short-circuit protection, to detect and break, as quickly as possible, abnormal currents generally greater than 10 times the rated current (In).

b overload protection, to detect increases in current up to about 10 In and switch off the starter before overheating of the motor and conductors damages the insulation.

This protection is provided by specific devices such as fuses, circuit breakers and thermal overload relays, or by more integrated devices offering several types of protection.

Protection functions Short-circuit protectionGeneral

A short-circuit results in a very rapid rise in current which can reach several hundred times the value of the operational current. The consequences of a short-circuit are dangerous to both equipment and persons. It is therefore imperative to use protection devices to detect the fault and very quickly break the circuit. Two types of protection are commonly used:

b fuses (cutout) which break the circuit by melting, which then requires their replacement,

b magnetic trip circuit breakers, often more simply called "magnetic circuit breakers", which only require re-setting to put them back into service.Short-circuit protection can also be built-into multifunction devices such as motor circuit breakers and contactor-breakers.

The main characteristics of short-circuit protection devices are: b their breaking capacity: this is the highest prospective short-circuit current value

that a protection device can break at a given voltage. b their making capacity: this is the highest current value that the protection device

can make at its rated voltage in specified conditions. The making capacity is equal to k times the breaking capacity.

Fuses (cutouts) Fuses provide individual phase protection (single-pole), with a high breaking capacity in a compact size:

b mounted either in fuse carriers, b or in isolators, replacing the original links or shunt bars.

For motor protection, aM type fuses are used. Their design characteristics allow them to conduct the high magnetising currents that occur when motors are switched on. They are therefore unsuitable for overload protection (unlike gG type fuses). This is why an overload relay must be included in the motor power supply circuit.

Magnetic circuit breakers These circuit breakers protect installations against short-circuits, within the limit of their breaking capacity. Magnetic circuit breakers provide omnipole breaking as standard. For relatively low short-circuit currents, the operation of a circuit breaker is faster than that of fuses. This protection conforms to standard IEC 60947-2. The thermal and electrodymanic effects are also limited, therefore ensuring better protection of cables and equipment.

Protection functionsOverload protectionGeneral

An overload condition is the most frequently encountered fault. The symptoms are a rise in the current drawn by the motor and thermal effects. A rapid return to normal operating conditions is important.The actual operating conditions (ambient temperature, operating altitude and type of standard duty) are essential to determine the operating values of the motor (power, current) and to be able to select effective overload protection. These operational values are given by the motor manufacturer.

According to the level required, protection can be provided by: b overload relays and thermal overload relays (bi-metallic or electronic type) which

protect motors in the event of: v overload, by monitoring the current drawn by each phase, v phase imbalance or failure, by their differential mechanism. b relays with PTC thermistor probes (Positive Temperature Coefficient). b overtorque relays, b multifunction relays.

Overload relaysThese relays protect motors against overload. They must allow the temporary overload that occurs on starting and must only trip if the starting time is abnormally long.The overload relay will be selected according to the length of the starting time (tripping class) and the motor rating.These relays have a thermal memory (except for certain electronic overload relays, indicated by their manufacturers) and can be connected:

b either in series with the load, b or to current transformers placed in series with the load.

Bi-metallic thermal overload relays Combined with a contactor, these relays protect the line and the equipment against small and prolonged overloads. They must be protected against strong overcurrent by a circuit breaker or fuses. These relays may be used on an a.c. or d.c. system and are generally:

b 3-pole, b compensated, i.e. insensitive to ambient temperature variations, b with manual or automatic reset, b graduated with a "motor FLC" scale: allowing direct setting to the full load current

as shown on the motor rating plate. They can also be sensitive to phase failure: this is known as 'differential'. This function conforms to standards IEC 60947-4-1 and 60947-6-2. This type of relay is extremely reliable and is a relatively low cost device.

Electronic thermal overload relays Electronic thermal overload relays have the advantage of electronics which allow a more complex thermal image of the motor to be created.They can be combined with products having complementary functions, such as:

b temperature sensing via PTC probes, b protection against jamming and overtorque, b protection against phase reversal, b earth fault protection, b protection against no-load running, b alarm function.

Protection functions (continued) Overload protection (continued)Relays for use with PTC thermistor probes

With direct sensing of the stator windings, these relays can be used to protect motors against:

b overload, b a rise in ambient temperature, b a ventilation circuit fault, b a high starting frequency, b mechanical shocks, etc.

Overload (or overtorque) relays These relays protect the drive line in the event of a locked rotor, seizure or mechanical shocks. This is an additional protection.Unlike thermal overload relays, these relays do not have a thermal memory. They have definite time characteristics (adjustable current threshold and time delay).The overtorque relay can be used as overload protection for motors with long starting times or very frequent starting (for example, lifting hoists).

Multifunction relays b Overcurrent relays are limited when it is necessary to take into account problems

associated with voltage, temperature or special applications. New production or maintenance management needs have prompted manufacturers to offer products which provide not only adaptable protection, but also complete management of the motor and its load. They incorporate:

b current and voltage sensors (TeSys T controllers), b hybrid analog and digital electronic technology, b the use of communication buses for data exchange and control, b powerful motor modelling algorithms, b integrated application programs whose parameters can be set.

These products make it possible to reduce installation and operating costs by reducing maintenance and downtime.

TeSys U starters:The multifunction relay is incorporated in the motor starter. This solution is very compact with reduced wiring. It is limited to 32 A.

TeSys U controllers: The multifunction relay is separate from the power line and reuses the function blocks from the TeSys U solution. It can be used in conjunction with a contactor up to 810 A.

TeSys T controllers: The multifunction relay is separate from the power line and incorporates inputs and outputs. It can be used in conjunction with a contactor up to 810 A.
